Description

These monster cookies definitely live up to the name! They’re thick, soft, and loaded with M&M’s and chocolate chips. This recipe even includes a secret ingredient to enhance the flavor and texture. These can also be made regular or vegan!


Ingredients

Scale
  • 1 1/4 cup (125g) quick oats
  • 1 cup (125g) all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup (110g) unsalted butter (reg or vegan), room temp
  • 1/2 cup (140g) creamy peanut butter, like Jif or Skippy
  • 3/4 cup (180g) light brown sugar, packed
  • 1/4 cup (55g) granulated sugar
  • 1 tsp vanilla extract
  • 2 tsp molasses*
  • 1 large egg or 1 flax egg**
  • 1 cup (185g) M&Ms or UNREAL chocolate gems
  • 1 cup (185g) semisweet chocolate chips (reg or vegan)

Instructions

  1. Preheat the oven to 350F and line a large baking sheet with parchment paper.
  2. Combine the oats, flour, baking soda, and salt in a small bowl and set aside.
  3. In a large mixing bowl with a hand or stand mixer, cream together the butter, peanut butter, and sugar on medium-high speed for a couple minutes until light and fluffy. (see picture in post for reference). Scrape down the bowl.
  4. Mix in the vanilla, molasses, and egg until fully combined. Scrape down the bowl and give it another mix.
  5. Toss in the dry ingredients and mix just until the dough comes together. Remove from the mixer and fold in the M&M’s and chocolate chips using a rubber spatula.
  6. Using a large cookie scoop (2oz) scoop 5-6 cookies onto the baking sheet. Bake for 15-18 minutes or until lightly golden around the edges. If using a regular cookie scoop, bake for 12-15 minutes.
  7. Let the cookies rest on the baking sheet or a couple minutes, then transfer the cookies to a cooling rack.
  8. Enjoy!

Notes

*MOLASSES – You can’t actually taste the molasses in these cookies. It just helps to enhance the flavors and create a chewy-gooey texture.

**VEGAN EGG –  Sub one whole egg with one flax egg = 1 tbsp ground flaxseed mixed with 2 1/2 tbsp water. Let it sit and gel for 5 minutes before use.
